Pairing the balanced adjustable Ellipse 2nd stage regulator, with the hyper-balanced diaphragm 1st stage MC9 regulator, place this regulator at the very top of the Cressi range. The engineering and performance of this combination creates a high performance regulator that will compete with the best of them. The Ellipse Balanced 2nd stage has incorporated many of the characteristics of Ellipse. The Ellipse Balanced has a slightly larger housing which is made from a sound-absorbing material, and a new diaphragm that further improves the already very low inhalation effort of Ellipse... more

The Ellipse Titanium uses an elliptical housing for the second-stage regulator which is made from hi-tech polymers and titanium. The use of titanium and the polymer create a very lightweight regulator. All the internal components of the Ellipse are a dependable high performance downstream valve design. Once the valve has open the air is channeled by injection to the liquid silicone mouthpiece creating a venturi-effect enhancing the performance. On the top of the housing there is a flow deviator that acts on the Venturi effect, with dive/pre-dive switch... more
